Application led September 2, 17921. 'Serial No. 498,150',`

T 0 all fui/tom it may conce-m Be it'known that I, WALTER J. DUrrnr, a

of Great Britain.l and resident of the city of Fort William, Prov-V ince of (')nta-rio, inthe Dominion of Canada, have invented certain new anduseful Improvements in Car Loaders, described in the following specification and illustrated in the accompanying drawings, that form lpart o-f the same.V y

The principal objects of the invention are, to effect a saving `of time and expense in the loading of box cars', and-to wdevise fa construction of loaderwhich will be very simple tooperate but .strong and durable inconstruction. Q Y

' The principal features of the invention consist in the novel construction and arrangement ofparts, whereby a. pair of endless carriers supported upon a movable carriage are operated to carry the mate-rialV being loaded to the ends of the car, and whereby the carriers are manipulated and controlled. f l

In the drawings, Figure 1 is a side elevational view of my improved carrier shown in the loading position projected into a box car. l

` Figure 2 is a plan view. I Figure is .av front end elevational vieuTk showing the carrier extended.

In the loading of box cars with coal, stone and like material it` is desirable that the load be uniformly' distributed and this cannot vbe done with the"'ordinary chute.

In the present invention the loaderV which is formed of a pair of endless carriers adapted to extend toward each end Vof thev car is supported upon a,` frame l, hereV shown formed of a pair ofk I'V beams rigidly connected together bycross plates 3 extending Vacross the tops thereof. These I beams are supported upon a plurality of rollers 4 arranged upon shafts 5 supportedin brackets 6 carried on a suitable foundation 7-which is arranged adjacent tothe traclrway upon which cars to be loaded are run.

A series of rollers 8 are arranged inthe brackets 6 to engage the upper surface of the bottom flange of the'I beams tol hold the, frame down to the rollers and to ensureits retaining ahorizontal position. Y

Between the I beams2 and rigidly secured tothe foundation are a series of brackets 9 supporting the toothed rack 10 and the shaft 11 mounted in suitable bearings on the frame 1 and extending transversely thereof carries a gear wheel the bracket 10. On the shaft 11 is also mounteda worm wheel.v13 which is* Operated yby' aworm'121. The worm 14 isc/armed" on a sleevecon# l tina-iz; if EHC-E9* 12 ywhich meshes with trolled [by afriction' clutch 15A which is l mounted upon the shaft"16 'drivenfbythe motorlj A pair of fabricated frames18 are supported on the end oftheframe 1 projecting from ythe supporting rollers andA between these frames areljournalleda pair of shafts 19 `arranged adjacent to `the bottom .and upon each of'tliese shafts are pivot-ally supportedza pair of metalfplates 20 which form the? sides of the conveyers.

Shafts 21 extend between the'fouter ends of each pair of the plates 20 and upon-the Vshafts 19 andV 21 lare. 'mounted suitable sprockets. Thesesprocketscarry the end'- less carriers 22.' i Y Y* Cross barsl 23 are arranged 'between the plates 20 adjacent to the outer shafts Vand also at the inward ends, the inner ones'not being lshown' and between these cross bars and side plates are'supported met-alplatff formsftto support the'lade'ned carriers. 1 On the shafts 19A arevmounted pair of inter-meshingspur gearsgone of which isv f driven by a pinion 26. The pinion 26 is driven by ya spur gear'28 Ycarried on'a shaft 27 mountedA in'. suitablefbearings, and said gear 28 in turn is driven-by a pinion 29 con'- nected' with a friction clutch 30 mounted on the shaft'l. v{IhroughI this connection ythe motor operates 'the gears`25 to operate the endless carriersito move cutfwardlyfromv the centre -andto'lcarry material deposited thereon at the ends of said cfmveyers. Y

A Ypair of shafts 31 and'Z are mounted Y in the upper part of theframes 18y vertically therone above the other and are operatively connected withthesp'ur vgears v33 'and 34. The lowenshaft is operated Ybv a chain' which extends downwardly around a Vsproclmt carried on the shaft-,36 and connected by ajclu'tch 37' to a spur gear 38 mounted on ysaid shaft and opera-ted by a pinion 39 carried on one of-thjeshafts 19.

The upDe-r shaft 31 is provided with a pair of cable vdrums40 and pairs 'of cables i1 and 4.2 'are mounted uponsaid drums 'and extend v'outvvzndly tothe outei` ends of. the

pivotal carrier frames. The rotation of the upper shaft 31 causes the. raising of the carrier shafts and in order to maintain the carrier frames in the desired position a ratchet Wheel 43 is secured on the shaft 3l and said ratchet is engaged by a dog This dog is operated by a rod 45 extending horizontally to a point adjacent to the motor and is provided with a cani adapted to lift the ratchet dog.

A sleeve 46 is mounted on the rod 45 and to this sleeve is connected a crank arm 47 to Which is connected aA link 48 operatively connected With a clutchz member 37 so that said clutch may be utilized as a brake When the dog holding the cable drums is, released.

'A lever 49 is arranged adjacent to the operator and connected with a clutch operating member 50 controlling the friction clutches 15 and 30.

lun the operation lof this device the car to beloaded is placed opposite to the loader, the frame l `of which is drawn back clear of the trackway, lVhen the door is opposite to the frame l the operator throws in the clutch l5 to operate the Worm which rotates the spur gear causing it to travel vover the rack l0 and carrying the fra-ine 1 outwardly so that the outer end is extended into the centreof theV car. The ,carriers are of course in they raised position shown in dotted lines in Figure 3 to pass through the door Way and when they have passed inside,the operator releases the dog and lowers said carriers by` manipulating the brake. The loading chute v51 is then introduced through the, opposite rdoor of the car and the material to be loaded into the car is borne on to the carriers which are operated by the manipulation of the clutch 15 to drivesaid carriers. A,

.An inverted V-shaped guard 52 is placed over the. junction ofthe twocarriers 'so as to prevent the material from piling and Jamming inv between. The carrierV be manipulated to move transverselyT .of the car during the loadingy operationrso that every portion Willbe properly loaded and as the piles of material at the ends of the car rise the carriers may be lifted by manipulating the lifting cables through the clutch 37. When the' car has been completely loaded the clutch 37 is operated to pull Athe carriers into vthe raised position and the frame l is then operated to withdraw the loader from the car. v Y I A car loader such as described may be manipulated with ease from one position to another and is very easily controlled.

lVhat I claim as my invention is l. In a car loader, the Combination With armovable carriage, a pair of upright frames at the outer end, a pair of shafts extending across said frames, intermeshing gears secured to saidV shafts, frames mounted on said shafts and adapted to extend outwardly, endless carriers carried in said frames operated from said shafts, a shaft extending across the top of said end frame, cable drums on said top shaft, cables secured to the outer ends of said pivotal frames and connected to said drums, means for rotating said drum shaft, a clutch controlling the operation of said drum shaft, and ratchet means for holding said drum shaft to retain said carrier frames in variousinclined positions.v
